Volunteers across Europe will pick up litter on Saturday 10 May, as part of a coordinated EU Clean Up Day. The event is particularly timely, as there are growing concerns that rubbish polluting Europe's land and sea harms wildlife and may ultimately affect human health.

Increasing amounts of litter are ending up in the world’s oceans and harming the health of ecosystems, killing animals when they become trapped or swallow the litter. Human health is also at risk, as plastics may break down into smaller pieces that may subsequently end up in our food. These are just a few of the problems emerging from the waste collecting in our seas.

The European Environment Agency (EEA) is launching a new competition for artistic depictions of waste in Europe. Each European generates approximately half a tonne of household waste on average. A lot of this so-called waste is actually a useful resource, but only two fifths is recycled, according to a recent analysis.

Austria, Germany and Belgium recycled the largest proportion of municipal waste in Europe in 2010. Although some countries have rapidly increased recycling rates, Europe is still wasting vast quantities of valuable resources by sending them to landfill, and many countries risk falling short of legally binding recycling targets.
